Abstract
Purpose: To systematically review factors affecting hip capsule thickness.
Methods: The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The terms "hip," "arthroscopy," "capsule," "capsular," and "thickness" were used to search the PubMed, Ovid [MEDLINE], Cochrane Database, and EMBASE databases from inception to January 15, 2024.
Results: The initial search identified 1,735 studies. Twenty-three studies were included in the systematic review. Eight reported the relationship between sex and capsule thickness. Seven reported that capsule thickness was significantly lower in women. Of the four studies reporting the relationship between capsular laxity and capsule thickness or Beighton test score (BTS), four studies demonstrated the association of lower capsule thickness in patients with capsular laxity or BTS ≥4. Of the six studies reporting the relationship between arthroscopic surgery and capsular thickness, two demonstrated significantly higher capsule thickness after capsulotomy with repair and two found significantly decreased postoperative capsule thickness without repair. One study illustrated that anterior capsule thickness was significantly smaller in patients with femoral torsion angle >20°. One study showed that neck-shaft angle was negatively corelated with anterior capsule thickness. Of the three studies that examined lateral central edge angle, two reported that lower angle correlated with thinner capsule thickness; one study reported the opposite result. Hip inflammatory disease was associated with thicker hip capsule.
Conclusion: Female sex, capsular laxity, BTS ≥ 4, higher femoral torsion angle, and higher neck-shaft angle were associated with a thinner hip capsule. Hip inflammatory disease and capsule repair after arthroscopic surgery were associated with a thicker capsule.
Level of evidence: IV, systematic review of Level I-IV studies.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
